A must equipment for any lab!


Average Rating 4.7

Application Area:

Cellular assays

PheraStar is really easy to use, to assess and define protocol in order to get reproducible data. Also changing the filter units is an easy procedure. In short time 96, 384 and 1536 well plate are readed, with the possibility to define controls or standard units. It is the kind of equipment each lab needs to have.

Amazing plate reader!


Average Rating 5.0

Application Area:

Proliferation assay plate reading

I really like the PheraStar plate reader because it’s so easy to adjust the parameters and so easy to visualise the changes in proliferation because of colour coding.

PHERAstar has exceptional reliability and flexibility; tech support EJ is amazing!


Average Rating 5.0

Application Area:

Drug Discovery Research

PHERAstar is the Must Have instrument to enable our fast-paced drug discovery research. I have been in the pharmaceutical industry for almost 10 years and had used a variety of microplate readers from different vendors. PHERAstar stands out to be top of the line product with exceptional reliability and flexibility. The extra bonus from purchasing PHERAstar from BMG Labtech is the after sales care - I'd like to give a big shoutout to BMG's technical specialist EJ (Edward “EJ” Dell) for his expertise, excellent customer service, and his "can do " attitude that helped us in many occasions to tackle technical challenges in setting up novel assays. It's a great pleasure to work with EJ and we are very happy with PHERAstar instrument. Highly recommend this product!

Extremely Easy to Use with Great Sensitivity


Average Rating 5.0

Application Area:

Genetic Marker Application

Not only is this instrument very easy to use, but it is also the most reliable and user-friendly instrument in our lab. We use our PHERAstar FSX daily for different fluorescence applications and standard absorbance readings, and it is fast, sensitive, consistent in performance, and reliable. The Microplate Stacker is a huge plus. Just load the plates and walk away. That is how easy and reliable it is.

We rely on PHERAstar readers as a core analytic instrument.


Average Rating 5.0

Application Area:

absorbance, fluorescence, luminescence, and homogeneous time resolved fluorescence assay development

The PHERAstar FSX instrument is a high quality, reliable, plate reader. Our assay development platform relies on PHERAstar readers for absorbance, fluorescence, luminescence, and homogeneous time resolved fluorescence. We have excellent experience with BMG as a manufacturer/ partner both in the knowledgeable and responsive sales reps and their quality technical service reps. The BMG MARS software provides easy-to-manage instrument control, customizable method protocol development with many available curve fitting tools and data analysis workflows that are powerful and easy to customize; all with a relatively shallow learning curve. Results report building is customizable, and data can be exported to software such as Excel for additional processing. The MARS software complies with 21CFR part 11 regulations for data integrity allowing for use in a GMP lab setting.

Easy to use with reproducible signals.


Average Rating 4.0

Application Area:


This reader is very easy to use. We use it for more or less all our experimentations reading fluorescence, luminescence, alpha lisa. We have purchased 4 readers in my service and they are really heavily used.

Review Date: 29 Sept 2022 | BMG LABTECH

Reliable, intuitive, great technical support


Average Rating 5.0

Application Area:

Detection of enzyme reaction products

I have used plate readers from a variety of companies and the BMG plate readers are by far the most intuitive to use and have been the most reliable. The pherastar is great for throughput and the clariostar has great flexibility for assay development. There is a large database of product application notes available to help in set up of new protocols and if there is no solution available there, their in house technical support is brilliant - helpful, easy to talk to and knowledgeable. Highly recommended!

The new PHERAstar® FSX from BMG LABTECH for HTS.

The most sensitive instrument for screening and assay development. Specifically designed for highest sensitivity and speed. Its unique features make it superior to any other microplate reader currently on the market.

With all the features you would expect from the Gold Standard HTS microplate reader and more, including:

  • The highest sensitivity for Fluorescence Intensity and Polarization
  • Fastest read times thanks to Simultaneous Dual Emission detection (including Alpha Technology)
  • A dynamic range of 9 decades for luminescence measurements
  • An ultra-fast UV/Vis spectrometer for full absorbance spectra (220 to 1000 nm) in less than 1 second per well
  • All microplate formats up to 3456-well
  • New generation laser for highest performance in TRF detection
  • Dedicated AlphaScreen®/AlphaLISA® measurements
  • Up to two onboard reagent injectors
  • Three integrated barcode readers
  • Advanced assay stability system

Thanks to assay-specific Optic Modules, you no longer need to worry about which filter or dichroic mirror is installed. These Optic Modules are configured with all the necessary optical components, with the appropriate module selected automatically by the PHERAstar® FSX. Up to six easily exchangeable Optic Modules can be accommodated in the PHERAstar® FSX at any time.


  • Filters and Optic Modules: standard filters from 240 - 850 nm, filters and Optic Modules optimised for specific applications, and bespoke solutions are available
  • Microplate Stacker: optimises microplate handling and increases throughput by providing rapid loading, unloading, restacking, and continuous feeding for up to 50 microplates
  • LVis Plate: microplate for low-volume DNA, RNA and protein quantification. It includes 16 micro-drop (2 µL) wells, a cuvette slot and optional performance testing features
  • Evaluation Plate: validates the optical functionality of BMG LABTECH microplate readers for quality control and/or qualification (IQ/OQ) purposes
